Randomly permute numbers {1, 2 ... n} what is the prob. digit k ends up in the i'th position Let's fix the position of digit k. We now can permute other (n-1) digits. The number of permutations is (n-1)! So the proba...
The probability is (I think clearly) $\frac{1}{n}$. For the number $k$ is equally likely to end up in any one of the positions. One can also conclude this in a more complicated way. There are $n!$ equally likely permutations of our $n$ numbers. By your reasoning, there are $(n-1)!$ permutations that...

Can you completely permute the elements of a matrix by applying permutation matrices? Suppose I have a $n\times n$ matrix $A$. Can I, by using only pre- and post-multiplication by permutation matrices, permute all the...
It is not generally possible to do so. For a concrete example, we know that there can exist no permutation matrices $P,Q$ such that $$ P\pmatrix{1&2\\\2&1}Q = \pmatrix{2&1\\\2&1} $$ If such a $P$ and $Q$ existed, then both matrices would necessarily have the same rank.

number of multiples of 4 that are multiples of 4 even if you permute their digits How many 4 digit numbers are multiples of 4 no matter how you permute them? (base 10)
A number written in base ten is a multiple of $4$ if and only if the two-digit number formed by its last two digits is a multiple of $4$. If these two digits are $ab$ in that order, clearly $b$ must be even. It’s not hard to verify that if $b$ is a multiple of $4$ (i.e., $0,4$, or $8$), then the two...

Permute Digits （递归、java） - CSDN博客
permute算法是求序列的全排列，对于字符串来说，就是将组成该字符串的所有字符按各种方式排列一下。可以通过递归实现该算法。递归的基准情形是：当字符串的长度小于等于1时，其全排列就是字符串自身，直接输出。如果字符串长度大于1，则遍历字符串中的每个字符，以该字符作为目的串的起始 ...

Can we permute the coefficients of a polynomial so that it has NO real roots? Let $P(x)=a_{2n}x^{2n}+a_{2n-1}x^{2n-1}+\ldots+a_{0}$ be an even degree polynomial with positive coefficients. Is it possible to permute ...
Yes: put the $n+1$ largest coefficients on the even powers of $x$, and the $n$ smallest coefficients on the odd powers of $x$. Clearly the polynomial will have no nonnegative roots regardless of the permutation. Changing $x$ to $-x$, it suffices to show: if $\min\\{a_{2k}\\} \ge \max\\{a_{2k+1}\\}$,...

Notation for Permuting Sets If I have some arbitrary sets $A_i : i \in I$ and I want to permute their intersections pairwise, how would I write such a permutation? Would I use some permutation tensor? Essentially I wa...
You want $$\left\\{A_i\cap A_k:\\{i,k\\}\in[I]^2\right\\}\;.$$ The notation $[X]^\kappa$, where $X$ is any set and $\kappa$ is any cardinal number, is defined to be $$[X]^\kappa=\\{S\subseteq X:|S|=\kappa\\}\;,$$ the family of subsets of $X$ of cardinality $\kappa$. This is a standard notation, but ...
